Survival analysis of recurrent squamous cell carcinoma of the lower oral cavity treated by surgery.

The aim of the present study was to investigate the survival of individuals with squamous cell carcinoma of the lower oral cavity who underwent surgical treatment and experienced recurrence, considering the site of the recurrent disease. A retrospective longitudinal study was conducted, comparing the survival rates of patients with and without recurrence and considering the site of recurrence (local, regional, distant). Statistical analysis was performed with SPSS and a p-value ≤ 0.05 was considered significant. The sample comprised 150 patients, 59 (39.3%) of whom experienced recurrence. Local recurrence occurred in 35 patients (23.4%), regional recurrence in 17 (11.3%), and distant recurrence in seven (4.6%). The average survival of participants with local, regional, and distant recurrence was 12, five, and two months, respectively. Patients with recurrent disease had worse survival than those who did not (P < 0.001). Patients with local recurrence had better survival than those with regional/distant recurrence (P = 0.011). All patients with regional and distant recurrence had deceased by the last follow-up. In conclusion, patients with local recurrence of squamous cell carcinoma of the lower oral cavity treated by surgery have a better survival rate than those with regional and distant recurrence. Local recurrence poses the possibility of curative salvage therapy.

Tolerance of early oral feeding in patients subjected to total laryngectomy.

BACKGROUND: The purpose of this study was to assess the tolerance of early oral feeding after total laryngectomy. METHOD: A randomized multicenter study was conducted that included 89 individuals subjected to total laryngectomy. The participants were allocated to 2 groups: early (n = 44), early oral feeding; and late (n = 45), late oral feeding. The participants in the early group were assessed as to acceptance of oral feeding, and their food intake was quantified. RESULTS: In the early group, the total energy expenditure and protein needs were not met through oral feeding alone at any time during the first 7 postoperative days. The times to attain 25% and 50% of the total energy expenditure and protein needs by oral feeding after surgery were 4 and 7 days, respectively. CONCLUSION: The patients subjected to early oral feeding failed to meet their caloric and protein needs through that route alone during the first 4 postoperative days and required complementary nutrition through another route. © 2015 Wiley Periodicals, Inc.

Spontaneous remission of a squamous cell carcinoma of the floor of the mouth.

Spontaneous remission is a rare, but well recognized event in oncology. Certain tumours, such as melanomas, hypernephromas and neuroblastomas, are known for showing spontaneous regression. Similarly, spontaneous regression of oral lymphomas, as well as oropharyngeal and recurrent tongue carcinomas, has been reported. Here, we present a novel case of a patient with a primary squamous cell carcinoma on the floor of the mouth whose tumour regressed spontaneously in three months, without any treatment. We also review of the literature on the spontaneous remission of oral cancer and discuss possible mechanisms for this phenomenon.

Retalho miocutâneo infrahioideo: reconstrução de defeitos cirúrgicos no andar inferior da boca / The musculocutaneous infrahyoid flap: reconstruction of surgical defects in the floor of the mouth

Introdução: O retalho miocutâneo infrahioideo (RMI) foi descrito por Wang em 1986. É utilizado em Cirurgia de Cabeça e Pescoço para reconstrução após ressecção de tumores, com sua principal indicação em tumores de andar inferior de boca. Objetivo: Avaliar, de forma retrospectiva, a exequibilidade e confiabilidade do RMI. Método: RMI foi utilizado na reconstrução cirúrgica em 25 pacientes portadores de carcinoma de andar inferior de boca. Apenas um dos cirurgiões do grupo tinha experiência prévia com a técnica. Os demais realizaram um único procedimento sob supervisão, a partir do qual os realizavam de forma independente. Resultados: Em três casos (12,0%) houve deiscência de sutura entre o retalho e o leito receptor, formação de fístula salivar e consequente deiscência de sutura no sítio doador. Em quatro pacientes (16,0%) houve epidermólise, com descamação e posterior reepitelização, sem necessidade de reintervenção cirúrgica.a Em dois pacientes (8,0%), houve necrose total da pele no terço distal do retalho, tratada com debridamento local. Não houve necrose muscular do RMI e não ocorreram complicações tardias. Comparando-se os três cirurgiões, não se observou diferenças nas taxas de complicações. Conclusão: O RMI é exequível no nosso meio, pois não demanda material específico e tem rápida curva de aprendizado. Os cirurgiões com vivência na especialidade podem facilmente incorporar essa técnica em sua rotina de reconstrução. As taxas de complicações são aceitáveis. O RMI é útil para reconstrução em cirurgia de cabeça e pescoço, notadamente para tumores iniciais de assoalho de boca e língua oral.

Introduction: The musculocutaneous infrahyoid flap (MIF) was described by Wang in 1986. It is used in reconstruction on head and neck surgery, with its main indication in tumors of the mouth floor. Objective: Evaluate retrospectively, the feasibility and reliability of the MIF. Method: The MIF was used in the surgical reconstruction in 25 patients with squamous cell carcinoma of the buccal floor. Only one surgeon of the group had prior experience with the technique. The other two surgeons performed the first procedure under supervision, then they performed independently. Results: Three cases (12.0%) had dehiscence between the flap and the recipient site, salivary fistula formation and subsequent wound dehiscence at the donor site. Four patients (16.0%) had epidermolysis with flaking and subsequent re-epithelialization without need for surgical intervention. In two patients (8.0%), there was complete necrosis of the distal skin flap treated with debridement site. There was no muscle necrosis of MIF and there were no late complications. Comparing the three surgeons , no differences in complication rates was observed. Conclusion: MIF is feasible in our country because it does not require special equipment and has fast learning curve . Surgeons with experience in the art can easily incorporate this technique into your routine reconstruction. Complication rates are acceptable. The MIF is useful for reconstruction of head and neck surgery, especially for tumors initial floor of the mouth and oral tongue.

Predictors of salivary fistula after total laryngectomy.

OBJECTIVE: To evaluate the incidence of pharyngocutaneous fistula after total laryngectomy and try to identify its predictors. METHODS: From May 2005 to April 2010, 93 patients underwent total laryngectomy. We evaluated complications during and after surgery and compared them with the following variables: gender, nutritional status, previous tracheotomy, tumor location, type of surgery, TNM staging, prior treatment with chemotherapy and/or radiotherapy, use of flaps for reconstruction and surgical margin. All patients presented with advanced neoplastic disease according to TNM. RESULTS: 14 (15.1%) patients developed postoperative salivary fistula. The mean time to onset of salivary fistula was 3.5 days, with a standard deviation of 13.7 days. Comparing salivary fistula with TNM variables, type of operation and neck dissection, prior tracheotomy, use of flap, preoperative radio and chemotherapy and surgical margin, there was no statistically significant difference (p> 0,05). CONCLUSION: The incidence of salivary fistula was 15.1% and no predictive factor for its formation was found.

The usefulness of a pectoralis major myocutaneous flap in preventing salivary fistulae after salvage total laryngectomy.

UNLABELLED: Salvage laryngectomy in patients treated with organ preservation protocols is associated with high rates of postoperative complications. The use of non-irradiated tissue flaps in pharyngeal reconstruction could reduce the incidence of these complications. OBJECTIVE: This study aims to evaluate the usefulness of the pectoralis major myocutaneous flap in preventing salivary fistulae during the postoperative period of salvage total laryngectomy (TL). MATERIALS AND METHOD: This retrospective study enrolled 31 patients operated between April of 2006 and May of 2011. All patients had advanced cancer at the time of the salvage procedure and had been treated with chemoradiotherapy or radiotherapy alone. Pharyngeal reconstruction was performed using pectoralis major myocutaneous flap in 19 cases (61%); primary wound closure occurred in 12 patients (39%). RESULTS: Salivary fistulae occurred in 16% of the patients who received the flap and in 58% of the patients with primary closure of the pharynx (p < 0.02). No statistically significant differences were noted between the groups with respect to the mean time for fistula formation, reintroduction of an oral diet, or use of a nasoenteric tube for feeding. CONCLUSION: The pectoralis major myocutaneous flap was found to reduce the incidence of salivary fistulae in salvage laryngectomy procedures.

Oncocitomas de glândulas salivares / Salivary glands oncocytoma

Introdução: Oncocitoma de glândulas salivares (OGS) é tumorbenigno raro das glândulas salivares, correspondendo a 1%dessas neoplasias. Aparece em geral após a sexta década de vida,sem preferência entre os sexos. Em 80% dos casos, localiza-sena glândula parótida. Material e Método: Apresentamos análiseretrospectiva de cinco pacientes com diagnóstico de OGS, sendoquatro em parótida e um em glândula submandibular, operadosnos últimos 13 anos em nosso serviço. Resultados: Todos foramsubmetidos à ressecção total da glândula. Há três pacientes comcinco a treze anos de seguimento, um operado há 10 meses, eum operado há quatro meses. Nenhum deles apresentou recidivaaté o momento. Comentários finais: O tratamento dos OGS écirúrgico e consiste na retirada do tumor com margens cirúrgicaslivres. A recidiva atinge índices de 30%, devido à excisãoincompleta do tumor ou à multifocalidade, o que demonstra aimportância do acompanhamento periódico dos pacientes.

Lateral pharyngeal diverticulum: a report of 3 cases.

Pharyngocele, or lateral pharyngeal diverticulum (LPD), is rare, as only a few cases have been described. This condition is characterized by local bulging in the piriform recess or in a vallecula. The diagnosis, which is clinically difficult, is made by barium-swallow examination of the pharynx. Surgical repair is indicated when symptoms are present. We report 3 new cases of LPD, and we discuss the etiology and clinical features of this entity. We also present a short review of the literature.
